The coordinate method for calculating the puncture route. Imaging markers represent a hyperintense line around the surface on the axial T2W image (a), T1W image (b), and sagittal T2W image (c). The formula [f(x a , y b ) = (a, b + c)] was used to design the puncture route (d). In the formula, the x-axis represents the imaging marker perpendicular to the body line, the y-axis represents the imaging marker parallel to the body line, a represents the distance from the y-axis, b is the slice thickness, and c is the slice gap used for the scan
